Debug Output

https://gist.github.com/olkoko/4ad4a520d8fbe37bf047a4f8e499f5a9

Expected Behavior

This should create a route table for VLAN with entry referencing Private IP in this VLAN.

Actual Behavior

Error: Cycle: oci_core_route_table.this, oci_core_vlan.this

Steps to Reproduce

See teraform configuration above.

References

This has been fixed for OCI Subnets back in 2018 by introducing oci_core_route_table_attachment.

Proposed fix is to enhance oci_core_route_table_attachment to support VLANs.
